Changing urls in visual composer's raw html block

Question

Visual Composer saves the raw HTML block as a base64 encoded (and url encoded) string in the database. My site needs to go from http to https, and I would need to change asset URL's used in these raw HTML blocks to be served with https. Clearly the Wordpress search/replace tool won't work here.

Does anybody know a solution for this?

Answer 1

I have this trouble too, and i wrote little script for this.

# WordPress VisualComposer RawHtml Base64  data base mass Replacing

For developers only!

This is little script for mass changes in wordpress visual composer database. 
You can change all domains, html code, scripts and etc, data that in base64 coded.

MAKE BACK-UP database table WP_POSTS!

All what you need, its take this in function.php at your theme folder.
Change sample data to yours needs.
Run url - your_site.com/replace_composer_html_raw_base64

If success - all data will be changed and you are happy now ;)
